To all whom it may concern:

Be it known that I, EinL JAGENBERG, a citizen of Germany, residing at Dusseldorf, Germany, have invented certain new and useful Improvements in Paper-Box Machines, of which the following is a specification. i

This invention relates to a machine for making paper boxes, paper bags andsimilar articles. w I The machine comprises a pair of opposed parallel guides and a pair of rotating heads that establish communication between the ends of the guides and form with them a continuous elongated track. Means are provided for intermittently advancing a core along said track, around which core the box is formed by successive devices arranged in proximity to the track.

In the accompanying drawing: Figure 1 is a front elevation of a machine embodying I my invention; Fig. 2 a plan; Fig. 3 a hori-.

zontal section on line AB, Fig. 1; Fig. 3 a detail of the guide head actuating mechanism; Fig. 4 a cross section'of the strip feeding and gumming means; Fig. 5 a side view thereof; Fig. '6 a. longitudinal section of the means for folding the blank around the core; Fig. 7 a cross sectionthereoflFig. 8 a plan thereof; Fig. 9 a section of the flap gumming means; Fig. 10 a section through the flap folding means; Fig. 1O a detail of the folders; Fig. 11 a plan of the flap fold- .ing means; Fig. 12 a section ofthe presser 'countershaft 52, while. wheel 56 by wheels.

. 56 and 56 drives shaft 52*.

The blanks are conveyed to the machine in 'the form of a stripe wound upon a reel 4 (Fig. 1) and passingv thence upward over an intermittently rotated drum 5 above which is arranged a tension roller 15. Drum 5 receives its motion from shaft52 and cam 6 that intermittently reciprocates rack 7.

This rack engages pinion 8, thesh-aft of which carries an arm 9, to which is fulcfumed a pawl 9*. During the ascent of rack 7, pawl 9 engages a ratchet wheel 10 which is 'operatively connected to drum 5, so that the latter is taken along. During the descent of rack 7, pawl9 passes freely over the teeth of wheel 10, so that drum 5 is not actuated. In this way the drum advances the strip at each motion of the ratchet wheel for the length of one Work piece.

In proximity to drum 5 is arranged a shaft 12- carrying a disk 11 and an arm or segment 12. During the rotation'of the shaft, the parts 11, 12 contact with a disk 14, that dipsinto a glue box 13 (Figs. 2 and 4) so that they will transmit the adhesive to strip a passing over drum 5. Durin this operation disk 11 williprovide the strip at one of itsedges along its entire length with an adhesive strip,iwhile arm 12will apply the adhesive' at. thefcenter of one. of the blanksides asfindicated by dotted lines Fig. 15. v

Strip a passes from drum 5 between table 16 and an idler 16 to the folding means located at point A. Here the work piece is severed from the strip by means of shears having a fixed jaw 18, and a movable jaw 19. Movable jaw 19 is extended rearwardly beyondlits fulcrum 20, and is by link 21, two 1 arm lever 22, and rod 24 actuated by cam.

of said rails and provided with a suitable Heads 28, 29 are intermittently rotated and convey the r number of core guides 35.

cores 25 from one rail to the other. The heads are mounted onvertical spindles 80, rotated by shaft-31 through bevel wheels 32.

there are guides 35 on each head, four teeth being shown. Upon shaft 31 turns an arm 33, carrying pawl 34 and linked to a lever 135, which is. fulcrumed at 36 and is operated -by cam 37. In this way pawl 34 will at ,each motion advance ratchet wheel 32 a tluarter turn, so that heads 28,'29 are intermittently rotated 1p like manner. In

Shaft, 31 carries a ratchet wheel 32? (Figs. 1 and 3) having as many teeth as I 65 raise the plate. As soon as a work piece is order to so arrest the heads that their guides 35 are held directly opposite to rails 26, 27

there is provided a bolt 36 (Fig. 13) having a reduced end or tenon that passes through a cross piece 37 and is connected to a bar 39 by nut 38. Bar 39 is by springs 40 yieldingly connected to a fixed plate 41 of the machine frame. To cross piece 37 is ivoteda rod 42, which by lever 44 pivote at 43, is operatively connected to a cam 45 'of shaft 52, so that cross piece 37 is inter- I mittently raised and lowered. After a. head 28, 29 has been turned, cross piece 37 is raised, toliberate'rod 39, which by springs 40 is drawn upward together with bolt 36*, so ,that the latterwill enter a notch 46 of the head and thus lock the latter in position. To cross piece 37 is connected a guide. pin 47 movable in the machine frame, and serving to prevent a lateral deflection of the cross piece during its movement. To cross piece 37 is further secured a slotted oblong guide or yoke 48 (Fig. 14) engaged by a roller 51 of anarm 50 having pusher 50'. During the ascent of cross piece'37 guide 48 will move arm 50 opposite to that guide of head 28, which occupies the same plane as rail 26, so that the pusher will slide the core out of guide 35, and int-o the fixed gulde rail 26. The movement of arm 50 is effected from shaft 52, by cam 57 and arm 58, the latter being secured to a spindle 59, car:

. rying toothed wheel 60, that bytransmission 61, 62 actuates a rack 63. o the latter is connected' arm 50, which i thus intermittently reciprocated. During the motion of thearm toward the left (Fig. 2 and arrow comprises a pair of platens 17 slidably su ported on frame 64, and having lugs 10 that extend over bolts 65, secured to said frame. Within lugs 17 are formed slits engaged by pins 6.6 of arms 67, fast on rods 68, which are by arms 69 operatively connected to cams 7 O. The latter will'by arms 69- impart alternate movement to rods 68,

- which'in turn by arms 67 will horizontally reciprocate platens 17. Frame 64 is by cross piece 71 vertically movable on rods 68.

Cross piece 71 is by link 72 connected to a two arm lever 73 turning on: shaft 31, and actuated by rod 74 from cam 75 of shaft 52. To cross piece 71 are pivoted two arm levers 125 which by springs 126 are held in the position shown in Fig. 6. To the cross piece.

' is further slidably secured by rod 76, a plate 77 influenced by springs 78, that tend to pushed over platens 17 and is cut off from I low platens 17, and their upper ends are by springs 126 yieldingly forced against the core, to press the upturned sides of the work piece against the same. The upward movement ceases as soon as platens 17 become horizontallyalined at their lower edge with the upper face of core 25. Rois 68 are now turned by cams 70, so that platens 17 are consecutively advanced over the core (arrows Fig. 6). The platens will during this movement grasp the ends of the work piece projecting above the core, and will fold the same over each other, so that the Work piece assumes the shape shown in Fig.- 16. The folding device is now retracted and the work pieceis by presser foot 115 tightly held against the upper side of the core (Fig.

.12). Foot 115 is rotatable on the core carrying slide, and is provided with an arm 11 6, havlng an upper reduced section and a col- "lar 117. Whenthe work piece moves toward A, foot 115 is by guide-rail 118 (Fig.

' 2) with collar 117, held in the position indicated' by dotted lines Fig, 12. At A the re duced section. of the arm passes behind a disk or abutment 124 carried .by rod 119 which is linked to a shaft 120. This shaft is connected to a crank arm 122 spring pressed against an eccentric 121 having an undulating operative surface and fast on an intermittently rotated shaft 31. The eccentric on turning will so advance disk 124 that it will liberate presser foot 115 (Fig. 12),.which will now be spring pressed against the core,

so as to force the workpiece against the same. Heads 28, 29 are now turned, so that.

a new core is pushed into guide 26, while the old'core is moved from A to B. Here a rod 80 is" guided vertically movable in the machine frame. This rod is provided with an upper arm 81, and-is at .its lower end coupledto a rod 82.actu ated by cam 83 of shaft 523 To arm. 81 are secured two plates 84, i

and an upper folder 85 extending across said plates. There is further provided avertically movable rod .86, carrying a lower folder 87 arranged in a plane with folder 85 and actuated by rod 88 from cam 83. Vhen a core with the work piece arrives at B, cam 83 will by rods 88,86-raise folder 87, so'that the latter will turn up the bottom flap of the work piece that projects beyond the end of the core (Fig.17). '-Simultaneo1 1sly cam 83 will lower arm 81, so that plates 84 will be pushed over the protruding side flaps of the work piece. When folder 87 has reached substantially its maximum elevation, folder 85 Wlll engage the protruding top flap of the work piece, after which folder 87 is lowered. Folder 85 in descending will turn down the top flap and press the same against the upturned bottom flap which has previously been gummed. After arm 81 has again ascended, the work piece is moved toward containing tank 93.

on a shaft 98, an arm or folder 99 of whichis provided with a pin 100, that engages a slit 101 of the jaw. Jaws 97 are influenced by a spring 102, which tends to turn the jaws in the direction of the arrow (Fig. "10) such tendency being normally opposed by pin 100. Shaft 98 carries a pinion 98 en-- gaging a rack 103 actuated by cam 96 of shaft 52. When a work piece arrives at C, cam 83 will lower rack 95s that disks 94 i will pass along the inner si es of the laterally extending flaps of the work piece. Back 103 then descends to turn shaft 98 with 'arm 99 "in the direction of the arrow 4 formed flap, Fig." 20.

ment of the core toward point D, it is pushed into a guide 35 of head 29, which (Fig. 10) and thus liberate jaws 97. The

latter by spring 102 are turned inward to press the protruding flaps against gumming roll 94, so thatthe flaps are coveredby an adhesive on their'inner sides. As a further advance of jaws 97 is checked by disk 94,

arm 99 alone will continue to advance, such advance being permitted by slit 100. The

on being turned conveys the core to point Here there is provided a plunger 105 movable radially toward the head (Figs. 1 and-2). Plunger 105 is byrod 107 and cam 106 pressed against the end of the core and consequently against the bottom of the work piece, so that the bottom forming fiapsare pasted smoothly and firmly together. Plunger 105 being retracted, head 29 again turns to carry the core to point'F, where it is conveyed from thehead into the fixed guide rail 27 and thence intermittently to points G, H, J and K. During this operation, the transmissionfrom the head to the fixed guide is effected by arm 50 and abutment 52 as previously described with relation to head 28. 1

At the points G, H, J and K are duplicated the devices located at points A, B, C and D, which duplicate devices surround the previously formed box by an outer box.

Thus the machine will form a compound box formed of two nested sections. is ejected from the machine at point L, by a slide or stripper 107 which by cam 108 and rod 109 is intermittently reciprocated along the core, The cores are made of uniform cross sections throughout their length,

so that the finished boxes will have a corresponding shape. To permit a ready stripping ,of the box off the core, the latter is composed of two sections connected by pivoted links 110. The upper core section is connected to a rod 111, having roller 111 which by spring 112 ,is pressed against a rail 113, arranged intermediate guides 26, 27 and'parallel thereto. Rail 113 is so The box.

shaped that during the movement of the I core from A to K, rod 111 is pressed outward against action of spring 112, so that the upper core section is raised off the lower section by righting links 110 (Fig. 12). At L the width of rail 113 diminishes so that rod 111 is retracted by spring 112, thereby folding links 110 and lowering the upper core section upon the lower section. In this way the height of the core is reduced, so that itfits but loosely into the box (Fig. 1). A rail 118 arranged in front of point L, is so shaped that when core 25 arrives at this point, presser 'foot 115 is retracted from the core, so that the box isliberated. Between points E and G there is also provided a guide rail 118, and at, G is located a disk 124, so that presser foot 115 is retracted from the core, prior tothe formation of the outer box section, and is advanced after the having-coraguides and adapted to convey the cores from t e end of one guide way to the opposed end of the other guide way, and paper folding means adapted to cooperate with the cores.
